The type of structural information obtained from the different types of experimental parameters used to calculate pE-DB ensembles

Experimental parameter	Major conformational information for IDPs
NMR CSs	Local structural propensities (poly-proline II, α-helix and β-strand populations)
NMR PREs	Detection of distances between regions distant in primary sequence (one containing a spin-label)
NMR RDCs	Local structural propensities
	Cooperativity of secondary structures
	Transient long-range interactions
NMR spin relaxation (¹⁵N, ¹³C)	Differential rigidity
NMR spin relaxation (¹⁵N, ¹³C)	Local dynamic timescales and amplitudes
NMR relaxation dispersion	Characterization of weakly populated states using CSs/RDCs (see above).
NMR relaxation dispersion	Conformational exchange on micro-millisecond timescales (folding/binding)
Small angle scattering (SAXS/SANS)	Pairwise distribution function of long-range distances
FRET	Long-range interactions
